Interface Summary
BinaryMetadataUpdatedListener: Interface allows any component to register for events of binary metadata updates.

Class Summary
BinaryMetadataKey: Key for binary metadata.
CacheObjectBinaryProcessorImpl: Binary processor implementation.
CacheObjectBinaryProcessorImpl.TestBinaryContext
IgniteBinaryImpl: `IgniteBinary` implementation.
MetadataRequestMessage: As `DiscoveryCustomMessage` messages are delivered to client nodes asynchronously it is possible that server nodes are allowed to send to clients some BinaryObjects clients don't have metadata for.
MetadataResponseMessage: Carries latest version of metadata to client as a response for `MetadataRequestMessage`.
MetadataUpdateAcceptedMessage: Acknowledge message for `MetadataUpdateProposedMessage`: see its javadoc for detailed description of protocol.
MetadataUpdateProposedMessage: MetadataUpdateProposedMessage and `MetadataUpdateAcceptedMessage` messages make a basis for discovery-based protocol for exchanging `metadata` describing objects in binary format stored in Ignite caches.
